System of refrigeration machines, heat exchangers for air conditioning has bivalent mode with plate heat exchangers, refrigeration machines producing refrigeration power simultaneously

摘要

The arrangement has plate heat exchangers (PWT) and refrigeration machines (KM) producing refrigeration power simultaneously in bivalent operation and the cold water coming from the cold water network is branched off before it enters the refrigeration machine and first passed via the plate heat exchanger and then to the refrigeration machine.
